SPECIFICATION forming part of Letters Patent No. 350,984, dated October 19, 1886.

Serial No. 150,110. [No model.)

To all whom it may concern:

Be it known that I, JACOB H. LINYILLE, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Printing- Telegraphs,of which improvements the following is a specification. 4

My invention relates to a printing-telegraph system and apparatus of the class in which rotating typewheels controlled by escapements are used in connection with impression devices operated by electro magnets, and so organized as to be employed for printing messages, stockreports, and other financial or commercial matters with increased rapidity and accuracy in page form on sheets of paper, or upon continuous rolls of paper, in lines, in paragraphs, or in columns-that is to say, telegraphically printing messages, stock-reports, &c., similar in form and arrangement, on the transmitting'instruments imnltaneously with their transmission to a receiving instrument, or printing on instruments which may be combined or which may be so organized as to be operated interchangeably as a transmitter or receiver, or which may be so organized as to be operated as an independent transmitter or receiver, the change from a combined transmitting-instrument to a receiving-instrument being readily accomplished without auxiliary gearing 0r motive power, through the manipulation of a switch, as hereinafter fully explained. I

My invention consists, generally, in the organization of the following systems of apparatus, and of combining in one or more instru ments all or any of the specific features as may be desired for the particular purpose, embracing, first, a paper-carriage with suitable feeding mechanism applicable to and susceptible of use in such combined transmitting and receiving instruments or in separate and independent transmitting and receiving instruments for telegraphically printing on flat pages, 850., from a continuous roll of paper; second ly, improved devices for feeding the paper to space between lines by the recoil movement of the carriage during its excursion; thirdly, 7

suitable mechanism forbringing the papercarriages of any number of receiving-1nstru ments into unison for cutting out of circuit all of the instruments connected in a continuous circuit, and for closing the circuit or circuits of such particular instruments as it may be desired to print the message on, through suitable mechanism and electrical devices operated from any transmitter in such series of instruments; tourthly, a novel construction of indicator-plate in a transmittirig-instrument, with radial circuitclosing arms and characterrods actuated by the depression of any charter-key, as will be hereinafter more particularly explained, and, finally, the organization of the electrical circuits for operating any or all of the combined instruments as receivers from any transmitter in the series, or for operating any number of instruments organized as receivers on separate lines radiating from a transmitter located at a central station.

The paper-carriage carrying the roll of paper upon which impressions are to be made traverses back ward and forward on a platform extending from the rear of the transmitting or receiving instruments or combined instruments, and supports the paper-rollers, circuitinterrupting switches, feeding rollers, and mechanism operating therewith, and having guides for supporting the paper in. a vertical position behind the type-wheel and contiguous thereto, so that the impressions made upon the paper occupy an unobstructed view at all times in front of the operator on a transmitting-instrument, and the impressions recorded on a receiving-instrument are in like manner visible to and convenient for reference by recipients, thereby rendering the invention especially valuable for recording long messages, stockquotations, 8:0.

\Vhen a series of page-printing telegraphinstruments are employed on continuous telegraphic lines, it becomes necessary to bring the respective paper-carriages to unison, in order that all the instruments may commence spacing letters in a line from similar points with reference to the margin of the paper on all of the instruments. To accomplish this result it is essentially requisite to lock each paper-carriage at a predetermined point, or preferably at the end of its retrograde movement,and to maintain it in such position until all the carriages in the series are in similarpositions, and then, by simultaneously releasing the respective carriages, to cause them to travel in unison.

It is essential in printing-telegraphs to provide means whereby a transmitting-operator may be capable of cutting out of circuit all the recei'ving-instrunients in a series, and of connecting in circuit ad Zibitmn the particular receiving instruments in the series on which it may be desired to record the impressions.

Without a unison device page-printing in paragraphs in columns, 820., in a series of connected instruments is impracticable, and without a cutout and circuit-closing device to individualize the instruments the same message would be printed simultaneously on all the instruments,involving expensive waste, unnecessary resistance in the circuit, and an appreciable increase 'of battery-currents, and especially obviating the essential requirement of secrecy in transmission.

To overcome these obj ectionable features is one of the objects of my invention, which I accomplish by utilizing the force of the recoiling paper-carriage for breaking the circuit through the operative electro-magnets of the receivinginstruments at the moment the left-hand margin of the paper has been reached, and automatically shunting the line-circuits by branch lines running in reverse directions through the coils of a differential electromagnet, one coil of which electro-magnet revolves the circuit-closers by a step-by-step or ratchet movement, and when these circuit-closers are revolved to a predetermined point in their peripheries they close the main lines around the break and through the electromagnets of any instrument to which it may be desired to transmit a message, leaving the remaining receivers inthe series inoperative, or they close the circuits of all the instruments in the series simultaneously after the papercarriages have been brought to unison. Motion is imparted to the revolving circuit-closers by a differential electro magnet in the branch circuit through which is sent over one line a number of electrical pulsations corresponding to the number of the instrument in the line which it is desired to bring into circuit, or to print on, numbering, of course, from a terminal station. One pulsation brings a single metallic bearing on the insulated circuit-wheels into contact with circuit-springs which close the line around the break to the instrument numbered, say, one, without, however, breaking the branch circuit. Two pulsations break this circuit again in number one,

rotating the metallic bearing of number two in to contact with its circuit-closin g springs, and so on in succession, one instrument of a higher number is brought into circuitand the preceding one disconnected until the instrument is reached on which it is desired to print the message. This restores the main circuit through the circuit-closing device until one pulsation is sent simultaneouslyover both lines by the releasing-key, or otherwise, which, while releasing the u'nison-latch oi' the type-wheels, closes the local printingci'rcuit, operating to move the paper-carriage one notch, thereby breaking thebranch main-line circuit through the circuit-closing electro-magnet, and restoring the original line to that particular instrument. The circuit-breaker to send pulsations is preferably a revolving circuit breaking wheel with as many makes and breaks as there are instruments in the line, and with a registering-dial on which is indicated the number of instruments connected in series or otherwise. A pointer on this dial indicates the number of pulsations sent to line and the relative movement of all the circuit-closing de vices. The circuit in the transmitter to this circuit-breaker is a branch of the main line normally broken when the circuit-breaker is stopped on a break or at zero.

After the transmission of a message each individual operator turns his circuit-breaker to zero, thereby enabling any operator starting from the zero-point to revolve the circuitclosers of all the instruments in the series until the desired receiving-inst-rument, as indicated on the dial operated, is in circuit. All the instruments, or any number, may be simultaneously connected by adjusting the circuit-closing contacts in the revolving disks so as to close the circuits simultaneously. To bring the circuit-closers to the same initial point, or to unison, a mechanical device is placed on the shaft of the circuitclosers,which looks it at a point corresponding with the zero of the dial, and an ordinary electro-magnet is placed in the first branch circuit above mentioned, with both lines passing independently through its respective coils, rendering it inoperative by impulses on one line while the differential electro-magnet is rotating the circuit-breaker, yet operative to release the uni-.

not be moved when. pulsations are sent to move the paper-carriage. The main-line cir llO IIS

cuits in the transmitter are broken at the main -line circuit-breaker when the typewheels stand at unison during this operation.

The transmitting-instrument may be organized similarly to the other instruments, and its circuit-closers operated synchronously. One ot the main-line circuits is normally connected through the coils of an electro-magnet which responds only to prolonged impulses on this line, its armature-lever being linked to a rocking arm held laterally by fixed aws, and through which a square shaft carried by the paper-carriage freely moves. This shaft actuates levers and pawls, which, at each impulse through this electro-magnet (at any position of the paper) revolves the feed-rollers one notch, feeding the-paper the space between two lines. The other main line is normally the same.

connected through another electro-magnct, responding only to prolonged pulsations, the armature-lever of which magnet is coupled to a shaft to which the automatic device for releasing the paper-carriage is attached. One prolonged impulse on this line releases the paper-carriage at any point in its excursion, allowing it to recoil and feed the paper a space between two lines.

Fig. 2 is a side elevation, partly in section, of the same. Fig. 3 is a top or plan view of the paper-carriage and mechanism operating therewith.

Fig. 7 is a detailed view of the unison fusee or spiral. Figs. 8 and t) are respectively theoretical diagrammatic views showing the arrangement of the electrical circuits and operative mechanism embodying my invention in combined transmitting and receiving instruments. Fig. 10 is a front elevation of the dialplate and individualizing circuit-breaker; and Fig. 11 is a longitudinal section of a combined transmitting and receiving instrument, showing, also, the paper-carriage and paper-foeding and individualizing mechanism.

In order that the description and operation of the receiving-instrument may be fully appreciated, I will now describe, by reference to the drawings, the principal features and elements embodying a transmitting-instrument and the mode of transmitting currents of electricity to a receiving-instrument.

A key-board, B, rigidly secured to the baseplate A of the instrument, is arranged somewhat similar to the key-board of a type-writing machine, with buttons, arranged in concentric arcs, on which are engraved letters, figures, punctuation marks, &c., with blank and unison keys, also arranged in concentric ares, with a blank key, b, for spacing between words, a unisoirkey, b, for releasing the insulated rod I), a key, b", for releasing the insulated unison-rod b'-' and unison-latch h, a key, If, for spacing between lines, a key, Z), for releasing the paper-carriage A at any point in its excursion, a key, If, for spacing between lines at any point in the excursion of the paper-carriage, a key, I), for releasing the unison of the individualizing cireuit-breaker, and a key, If, for duplicating letters.

The type-wheels U have letters, figures, punctuation -marks, and blank and unison spaces corresponding to the characters, fig- Q nres, &c., on the key-board B.

The character'keys, arranged concentrically on the key-board B, operate belterank levers b, resting upon a series of bearings, b rigidly secured to the curved guides b at different radii under the character-keys, and imparting longitudinal motion to the respective series of rods b, equal in number to the character-keys, lying horizontally and radiating from the same common center in which is placed the shaft b of the linecircuit breaker. Concentric therewith is placed a metallic segment of a cylinder, b, p referablyperforated with square holes I)", in series directly over each otherand equally distant from one another-that is to say, from center to centerthe entire number of holes b being equal to the divisions on the type-wheels C. These rods 1) pass through the curved guides If, that form the steps therefor, and are limited in their forward movement by shoulders 0 abutting against the metallic segment b, or pins 1), abutting against the fixed guides If, the rods 0 being normally held back by spiral springs b against or connected with one branch of the bell-crank levers b, the other branch supporting the keystems b", through which pass pins b, limiting the backward throw of the character-keys and rods b, and thereby bringing the terminals of these rods clear of the interior surface of the metallic segment 11".

()n the indicator-shaft Z), carrying the circuit-breakers N N, are as many metallic arms I) as there are series of holes b in the metallic segment I), these arms I), being secured to an insulated hub, If", on the indicator-shaft b", and located in the same horizontal planes with the respective banks of rods b", and on equal divisions of the circle corresponding with the number of banks of these rods. One of these rods 1) is a unison-rod, If, and is not operated by a character-key, but has a back ward motion to the forward one of a character-key, and vice versa, imparted to it by a rock-shaft, b', with depending arms I'-''- passing alongside of each radial line of rods 7), which is moved forward by pins I) in the rods 0, giving a reverse motion through a lever, Z), on the same shaft, and a link attachment, If, to the depending lever I), which, by a pin, If, on the unison-rod I)", withdraws it upon the depression of any character-key. The end of the unison-rod b", passing through the metallic segment I), is made of insulating material.

The circuit-breaker, escapement, compound, differential, printing, ratchet, and relay magnets, scape-wheels, spacing-wheel, clutches on a loose sleeve on the type-wheel shaft, centrifugal adjustable governor, paper-spring, and mechanism for actuating and operating these several elements and parts, form the subjectmatter, in conjunction with certain other featnres, of an application for a patent, Serial No. 175,131, filed by me under date of August 24, 1885; and I therefore do not wish to be understood as claiming these several elements and parts herein separately, but only in connection with new and improved features to be jeoted by the depression of a key beyond the y hereinafter fully described, which form in con- I junction therewith the subject-matter of this application.

On the indicator-shaft b is a circuit-breaker, N, single for single-line instruments, and double for instruments operated by double lines and escapements. As the type-wheel O revolves, the circuit-breakers N N on the indicator-shal'tb send electrical pulsations over the lines to operate alternately the escapement electro-magnets l and I, the compound or duplex relays H H, and diii'erential electromagnets J J, and rotate the typewheels C, while pulsations on both lines, simultaneously closed by the eleotro-magnet G, operate both the electromagnets H H, closing the local circuits to en'- ergize the paper-feeding electro-magnets and the printing electro-magnets of the receivers in combined or independent instruments. The bars I), insulated from the indicator-shaft b revolve so as to strike against any one of the character-rods b which may have been prosurface of the indicator-segment b into the path of the revolving arms I), and also to strike the insulated unison-rod Z) when none of the keys have been depressed. A circuitspring, I), bears on the insulated hub b", carrying these arms 12", and is connected with the binding-post b insulated from the machine.

When a key has been depressed, the typewheel 0 of the transmitter revolves as many characters as there are rods b between the starting-point or unison-rod b" and the character depressed. When it is stopped by the pin represented by the key and metallic rod 1), the circuit is closed from a local battery, Q, (one pole of which is in circuit with the body of the indicator'segment I)",) through the springs If", line Z electromagnet G, line Z key 1)", line F, spring 8, to the metallic block marked to send on the insulated commutator S, thence by spring 8, through line 2*, to the ratchet electro-magnet E, and thence to the impression electro-magnets D, and returning by line 1" to the other pole of the local battery Q. This energizes the ratchet electromagnet E and the impression electro-niagnet D of the transmitter, and causes the printinghammer d to impress the paper against the type-wheel O, printing the desired letter as depressed on the key-board B, and as indicated by the rod b in the indicatorseginent I), while the ratchet electro-magnet E draws back the arm a \Vhen the key is restored, the withdrawal of the rod 1) breaks the electrical contact,the hammer drecoils, the spring a withdraws the arm a and the pawl aflcatclr ing in a rack, A, in the paper-carriage A moves the same the space between the letter printed and the succeedingletter. The ratchet electro-magnet Eis secured to the plat-form A. carrying the paper-feeding mechanism.

When the type-wheels O of the transmitter and receiver have been stopped at the letter depressed, the local circuit of the transmitting-instrument is automatically closed, as de- .to its proper position.

scribed, which energizes the electromagnet G, attracting its tongue 9*, on which is an insulated bar, 9', for bringing the circuitsprings g g g 9 into contact, closing the circuit into both main lines simultaneously through branch lines Z Z Z Z, passing around the circuitbreakers NN, throughlines Z and P9, to the compound. or duplex relays H H, closing the local circuits by the relay-tongues h and the contacts h through the ratchet electro-mag nets E and printing electro-magnet D of the receivers in circuit, and simultaneously making impressions and feeding the paper the space between two letters on the transmitter and receiver. 7

The paper is normally held out of contact with the type-wheel C by an adjustable spring, 0 secured to the top plate, 0", of the machine by a pivoted stud, 0*, adjustable by a slotted arm, 0 moving on a stud-pin, c, on which is a clamping-nut, 0 for adjusting the spring 0" When the printinghammer d strikesthe paper 0, this spring 0 is pressed backward under the type-wheel O, and when the hammer d recoils the spring 0 moves the paper 0 out of contact with the type-Wheel 0, thus regulating the distinctiveness of the impression, preventing blurring, and enabling the printing to be done on flat surfaces.

The specific features embodying my invention will now be hereinafter more particularly explained.

In the drawings, Figs. 8 and9, as aforesaid, represent theoretical diagrammatic views of the principal operative devices and circuits in a combined instrument, or in separate or independent transmitting and receivinginstruments connected with line and local batteries, showing the indicator-segment and circuitbreaker of the transmitter, and devices for sending currents to a distant receiver, and for printing simultaneously on both instruments. The switch S and the. commutators S and S in Fig. 8are shown as turned to send and the local circuit closed to operate the printing devices of atransmitter, and to sendimpulses to theline of a distant receiver. If the switch S5 in Fig.9 be turned to line marked to receive, the circuits'will be changed by the commutators S and S, so that the currents from line will operate the compound or duplex relays H H, the escapement electromagnet-s I and I, and both branches of the differential electromagnets J J alternately, and the local circuit from the body of the instrument by line, as shown in Figs. 8 and 9, indicating electrical connection through the same into the tongue 71, thence through contact h, line Z springs 8 metallic block marked to receive, spring 8, lines Z Z and Z will operate the printing electro-magnet D and ratchet electro-magnet E of a receiver. Turning the switch S to receive also disengages the insulated unison-rod b in the indicator-segment b of a combined instrument, and engages a clutch, a, on the type-wheel shaft 0 with the loose IIO sleeve on the same, carrying the scape-wheels O" (3*, together with the star or letter-spacing wheel 0'' and disk-wheel G, with the spiral C for the unison-latch h.

I and I are escapement electro-magnets, which vibrate alternately by rapid alternating impulses of direct current sent over the lines by the circuit-breakers N N and springs a a a it. Their armatures operate double-pallet dead-beat or wedge-pallet escapement-levers it, each working into separate scapewheels 0 O on the same shaft, 0, so arranged that each electrical impulse permits the ad: Vance of the type-wheel O the space between two letters, and each break of the circuit a similar movement. There are half as many makes and breaks on each disk of the circuitbreaker and one-fourth as many teeth on each scape-wheel as there are divisions on the typewheel when two escapements are used, and the instruments are so arranged that they print a letter on each make or break of the electrical circuit.

The compound or duplex relays H H perform the function of drawing the tongue h into contact with the printingcircuit contact h when energized by the combined currents simultaneously entering at the binding-posts p p through the lines Z 1*", leading from a transmitter, and from these binding-posts the currents pass by lines Z Z' to the springs s 8, contacts marked receive of the commutator S, and spring 8*, thence by line Z through the electrounagnet L, thence by line Z to the differential electromagnet J, thence, say, to the right around the differential electro-inagnet J and by line Z through the coils of the escapement electro-magnet I, and thence by line Z through the coils H. of the compound relay, and thence, again, by the line Z to junction with the main line Z the other line, Z, from the spring a" passing through the electro-magmet K, thence by line Z to the differential electromagnet J, thence passing in a reverse direction, say, to the left, around the differentialelectromagnetJand bylinel' to the coils of the escapement electro-magnet l, thence again by line Z' around the coils H of the compound relay to the line I, and thence to the main line I, as hereinafter more fully described. Vhen the currents enter alternately by these lines, the two distinct electro-magnets H H comprising the system are energized alternately, resulting only in the vibration of the compound armature-lever 71;, (to which the tongue h is connected by a pivoted strap-coupling, 713,) without moving the tongue h. Coupled to the tongue h is a bell-crank lever. h, pivoted at one end, and its arm 1) extending over the horizontal diskwheel 0 Figs. 8 and 9, which has a spiral groove and projection,into and against which bears a pin on the unisonlatch h, rocking on the support h, and drawn downward and sidewise toward the shaft 0 of the type-wheel O by springs 11' in the side and below said latch, respectively. As the type-wheel revolves, the spiral carries the unison-latch h toward the periphery of the diskwheel 0, and by one or more revolutions it reaches the end of its path and locks the typewheel 0 at unison with the type-wheel O of the transmitter. If, however, the compound or duplex relays H H be energized by both linecurrents simultaneously, both armatures will be attracted, and the tongue It will be drawn forward, tripping the unison-latch h by the bell-crank lever Ir out of the groove of the spiral C, whereupon the arm h is thrown against the shaft of the type-wheel O, and thus begins its travel anew on the spiral; hence it is evident that the unison-latch it cannot lock the type-wheel G, if simultaneous printing-currents are sent one or more times during one revolution of the type-whee1.

Since it is necessary to send such impulses to make spaces and impressions, or to rotate the paper-cylinder, which should be done at a space or at unison, and since vibrations alternately over the lines are necessary to rotate the type-wheels to unison, and since printing is to be effected on makes and breaks of current, some other device is required, not only to hold the type at ablank space or at unison while printing-currcntsare si multaneouslysent over the lines actuating the tongue 7;, (displae ing the unison-stop and closing the local circuit of the receiver,) but to hold the type-wheel O rigidly at each character to be printed on breaks of line-circuit, and to release it by continually vibrating or attracting the armature while alternate impulses are passing over the lines through the escapement-magnets I and I. The differeutiallywound relay J, with its tongue j and arm j, is such a combination as is well adapted for effecting these results. The line-wires pass in opposite directions around the cores of the difterentiallywound relay J. The serrated or letter-spacing wheel 0 has as many indentations as there are characters and blank spaces on the type-wheel O. This differentially-wound relay J will become charged by the rapidly-recurring alternate impulses, yet will be inert when currents pass in both directions around its cores, and by its lug or projection j and springj lock the type-wheel O at any indicated character-space when the printing-current is sent simultaneously over the lines,'and will also lock it at blank or unison when once stopped at unison by the unison-latch It. It cannot alone arrest the type-wheel O at unison, because its armature is permanently attracted or vibrated by the alternate impulses required to move the scapewheels 0 C; but it can lock the type-wheel G at any letter or space when printing, or when the compound relays H H are energized by currents sent simultaneously over the lines to close the local circuit through the ratchet and printing clcctro-magnets.

The type-wheels O are brought into unison by withdrawing the unison-rod If of the transmitter through the action of the unison-key b, thus permitting the circuit-breakers N N to in ake one or more revolutions before releasing IIO IIS

After allowing the receiver to stop at unison the latch cannot be released, except by simultaneous electrical impulses on both lines. To prevent the operator from sending before the type-wheel of the receiver is released, I employ a unison-key, I), normally locking the unison-rod b and preventing any character-keys from being de- Before sending, the operator presses the releasing-key b the block b on the stem of thekey-bflreleases the unison-rod b" and character-keys, the insulation If on the back of the block Zr compressing the circuitsprings s 8 closing the branch local circuit 1 through the circuit-springs s 8", closed by the unisonrod b" and by lines Z Z Z Z Z, springs s" s, and line 1, energizing the electro-magnet G, which closes the circuit of both lines through leaving the typcwheels 0 locked at unison by the arm j on the tongue j of the differential electro-magnet J. The keys are now operated successively, keeping the unisonrod Zr withdrawn until it is necessary to effect unison. To avoid a closed circuit through the electromagnet G after the type-wheel O and circuitbreakers N N start, the local branch circuit 1 is automatically broken by the separation of I) is withdrawn.

A platform, A, is secured to the rear end of the base-plate A, having a supporting-frame, A for certain parts ofthe instrument. Upon said platform A are rails (L a, on which the paper-carriage A, supporting the paper-rollers A, paper-guides A", rack A, and circuitsprings z traverse, carrying and feeding the paper on which impressions are to be made in a fiat sheet, G, in a verticalrdirection in front of the type-wheel. Forward motion step by step to space between letters is imparted to motion of thelever a and pawl a? being effected A dog, a", retains the rack A" in position at each throw of the lever a and pawl a". The forward movement of the carriage is resisted by a coiled spring, (L5, or it may be by a weight, a, attached to a cord passing over a pulley, a This coiled spring is secured upon a shaft, (0, attached'to the platform A, one end of which spring is secured to an arm, A, depending from the carriage-frame A.

As the carriage A moves forward upon the rails a a, so as to feed the paper from left to C, the tension of the coiled spring to is increased, so that it is snfficient to return the carriage to its initial starting-point when the pawl c and dog a have been automatically released. Attached to the rear portion of the instruments is a straight inclined plane, a, the projecting flange a of which fits loosely into a notch, a, of the arms a, attached to the sliding pawls to, causing a vertical reciprocatingmotion of the arms a, and pawls a by the traversing movement of the carriage without the intervention of springs on the arms, thus obviating unnecessary resistance of springs 011 the arms a to withdrawthepawls. As the paper-carriage A recoils under the influence of the coil-springs a? or a weight, the arms a and pawls a are given a downward movement, imparting a rotary motion to-the ratchet-wheels c feed-rollers a, and guiderollers a", moving the paper forward and upward the space between two lines of the printing. The dogs a retain the ratchets a in position during the printing of another line, while the pawls a are gradually drawn upward by the plane until they enter the next notch or tooth of the ratchetwheels a, just, however, before the carriage again recoils.

The pawls a and dog a are released from the rack A by means of a tripping device consist ing of the T-shaped bar 0 and the two pins to a upon the upper side behind the pawl a and dog a, and pin a, extending downward to engage in the latch a The T-shaped bar a is pivoted to a shaft, a, extending through the platform, and is driven forward under the pawl a and dog a" by a projection, a on the carriage A, striking the projecting pin a, and causing it to becomelocked through-the action of the latch a. In this position the dog ais detached by means of the pin a and the pin a" engages in the spring-latch a, retain ing the dog to out of position with therack A", and the next attraction of the armature and lever a of the ratchet electro-magnet E de taches the pawl c from the rack A, causing it to lock on the pin c The carriage A immediately recoils, and just before it reaches the end of its travel astud, a, on the carriage A depresses the spring-latch a, permitting the T-shaped bar a to return to its normal position under the action of a spring, thus releasing the pawls a." and dog a, which re sume positions in contact with the rack A, ready to commence spacing between letters from the left-handmargin of the paper.

The plates Z are made of hard rubber or other suitable insulating material, and have projecting ribs 2 2, which are secured to the carriageframe A and move in unison therewith. Above these projecting ribs or flanges z 2, at one end thereof, are two long metallic springs, 2' z, standing free from the faces of the plates Z and pressing at one end on metallic bearings 2 on the projecting flanges z. Theinsulated springs a 2, attached to the platform A by insulated supports z, hear at their ends on the springs a7, and at right angles thereto preserving electrical contact during the forward movement of the carriage 5 2 .until they arrive at the ends of theirv path clear of thesesprings when'they snap ICC eircuitsprings by the next forward movement of the paper-carriage A. The p'rintinghammer d is operated by the electro-magnet D in the same local circuit with the ratchet-magnet E.

The operation of the apparatus when printing will now be described by reference to the theoretical diagrammatic views of two combined instruments and electrical circuits, illustrated in Figs. 8 and t) of the annexed drawings, showing the operative parts and circuits, when in the former view the switch S is set to send, and while in the latter view the switch S in a similar instrument 'is set to receive; both instruments being connected in series by a double telegraphic line; or the instruments may be two of a series of instruments looped into the main lines. The linebattery may be either located at one end of or on the lines, and the electrodes connected to earth at the terminal stations. lines from the main-line battery M are 0011- nect-ed to earth by line Z, and to the bindingposts 1) p by lines Z Z; thence by lines 1* Z to the circuit-springs s s in contact with the metallic blocks marked to send on the commutator S of the transmitter; thence to the springs s s by lines Z Z" to the circuit-breaking springs 01 a on the circuit-breakers N N; thence by springs 02 a to lines Z Z to the automatic circuit-breaker 0 through springs 0 0, 0, and 0" to lines Z and Z, springs e and s and by springs and z to lines Z and Z",- thence to the line bindingposts p p". Branch circuits Z Z extend from the springs 11. and a to the circuitsprings and g, thence by springs g and y" when closed by the movement of the tongue of the magnet G and lines Z and Z to the main lines Z and Z The branch lines Z and Z in this instrument, operative when employed as a receiver, Fig. 9, enter at the bindingpostspp, and are connected to springs s a by lines I I, and when the commutator S is turned to receive metallic contact is made with the springs s The commutator S be ing turned to receive, the main lines I 1", operativein a transmitting-instrument, are broken at the commutator S, and the main lines I F through the eircnitbreakers N N and lines Z I to the eommutator-springs s" s". From spring is" one line ol. the receiving circuit passes by line I, magnet Ii, line I in one direction-say to the right-around the differential magnet J; thence by line I" through the coils of the cscapement-magnct I; thence by line I through the coils H of the compound relay; thence by line 1" to intersection with the line thence to the circuit-breakers 0 and Z and the binding-postp" by the main line hereinbefore described. the other line, start- The double ing from spring a" of the commutator S, passing by line 1" around the coils of the electromagnetK; thence byline Z, passing in a reverse direction-say to the leftaround the differential electro-magnet J; thence by line P" to the coils of the escapement electro-magnet I; thence around the coils H of the compound relay, and by line Z to intersection with the main line I; thence by circuit-breakers 0 Z, line '1, to the binding-post p.

The main lines I and P connect with the receiving-instrument at the binding-posts and 2, Fig. 9, passing through the springs s and s and s and s in electrical connection through the metallic block receive on the commutator S, in the same direction as that just described for transmitting through the magnets K, L, J J, I 1, and H H, lines I and Z, (the lines Z and I now being normally broken at the commutator block marked Send;) thence to circuitlweaker O, springs 0 0 and o and 0",- thence by lines Z and I to the circuit'breakers Z, through springs z, z, z, and .2, lines I and I" to the binding-posts p p", from which the lines may be extended by lines Z and F to another instrument, or through a series of instruments or to earth.

A local battery, Q, is required at each trans mitting-instrument to energize the electromagnet G, for closing both liue-circuitssimultaneonsly through the electro-magnets H H of the receiver, in order to close the local circuit through the ratchet electro-magnet E and printing electromagnet D, for feeding the paper and for making impressions. One pole of the local batteryQ of each instrument is connected byline I to the binding-post p,- thence by line 1' to an nninsulated post, I), on the indicator-segment b,- thence, when contact is made between arm I) and a characterrod, 1), by insulated arm I), hubb circuitspring If", to the insulated post b thence by line through the coils of electro-magnet G; thence by line 1 through the duplicating-key b" to the circuit-spring s", metallic block marked to send on the commutator S, circuitspring s to line I, ratchet electromagnet ldfthence to printingelectro magnet D, returning by line 1" to the binding-postp and by line 1 to the other pole of the local battery Q.

In the receiving-iustrument, with the commutator S turned to receive, the local circuits pass by line Z into the body of the instrument at the nninsulated post If on the indicator-segment I), the insulated arms b of which now rotate out of contact with circuitclosing character-rods I). The current from the body of the instrument passes by a line, as indicated in Figs. 8 and 9, connecting the same with the compound or duplex relaytongue I), and to the contact h, insulated post it", line 1", to spring 5", to the metallic block marked to receive, Fig. 9, and spring 8*, lines I and l, to the ratchet electro-magnet E and printing electro-magnet D, and returning by line Z to the binding-post p thence by IIO ' .ments starts at the post I) on the indicatorsegment b, and passes by line Z to the key b normally open, thence by iineZ to the electroniagnet G, through this electro-magnet and line Z to the key t normally closed, to line Z, circuit-spring s", to the block marked to send, spring 8, line-Z, ratchet electromagnet E, and printing electro-magnet D, line Z,

to the postp and thence by line Z to the 10- cal battery Q. The extension or secondary branch extends from one end of key b by line Z, and is closed at the springs s and s by pressing the releasing-key Ziandinsulated cam l) of the transmitter, and is normally closed at the springs s and s", and automatically brokenat these springs s s" by the first movement of the insulated rod b withdrawn by pressing any character-key. This secondary branch is closed from springs 8 through line Z with the trunnions of key b andline Z of the primary branch local circuit. Pressmg the releasing-key b closes the secondary .branch of the local circuit Z at the springs s sfl'energizing the electro-magnet G, and the current sent over both main lines is available in the receiver, not only for releasing the unison-latch by energizing both'branches of the duplex electro-magnets, but for closing thelocal circuits at the contact it through the ratchet electro-magnet E and printing electro-magnet D, thereby moving the paper-carriage A one notch on the receiver, and this secondary branch local circuit Z being closed by its primarked to send in the transmitter, Fig. 8, springs s s, and line I through the ratchet electromagnet E and printing electro-magnet D, moving the paper-carriage one notch on the transmitter.

When a character-key has been depressed, the double circuit-breakers N N revolve, sending pulsations alternately over the lines to operate the escapement electro-magnet-s Iand I, Fig. 9, and to cause a synchronous movement of the type-wheels O. \Vhen any arm, I), Fig.- 8, strikes a projecting character-rod, b, in the indicator-segment b, the circuit from the local battery Q, is closed through lines Z Z, electro-magnet G, lines Z Z, tothe spring 3, block marked to send of the commutator S, spring s, line Z, ratchet electro-magnet E, and printing electro-rnagnet D of the transmitter,causing the lever'arm a and the pawl a to be drawn back ward soas to engage in a notch in the rack A and the hammer (Z, to impress the paper against a character on the type-wheel O. The electromagnet G, being energized, closes both branches of the main lines Z Z simultaneously through the springs y, g, g and '9 of thetransmittingsion. mary circuit through the metallic block instrument with lines Z, Z, and Z, and Z Z, Z, Z, and Z"- to the receiver, and the local circuit from the body of the receiver is closed by the action of the duplex relay H and the tongue h and contact h through lineZ, spring 8 metallic block marked to receive, spring 8 lines Z and Z to the ratchet electro-magnet E and printing electro-magnet D, thence by lines Z to post f, energizing these electromagnets and drawing back the arm a and pawl a and. the printing-hammer d, to impress the paper against the type-wheels ot' the receiving-instrument. The main-line currents at the same time passing through the differential electro-magnets J and J neutralize the same,

releasing the tongue yiand lockingthe typewheel 0 by the arm j engaging with the serrated wheel 0 Upon releasing a characterkey the local circuit is broken at the indicator-segment Z2 of the transmitter and the electro-magnet Gr is demagnetized, breaking the line-circuits at the springs g, g, and g, stopping the double-line pulsations and interrupting the local circuit at the contact h, the hammer d recoils, and the lever-arm a drawn backward by the spring (0*, moves the papercarriage A a space between two letters on 'both transmitting and receiving instruments.

If a character-key is depressed until a letter is impressed, and while the character-key is held down, the key b in the local circuit is depressed, momentarily breaking the local circuit in the transmitter, the type-wheels 0 will remain at the same letter, while the breaking and closing of the line by the electro-magnet G will cause a repetition of the printing and feeding movements, thereby rapidly repeating the impression of any letteror character, and greatly increasing the speed of transmis- If, while both instruments are standing at unison, pulsations are sent simultaneously over both lines by making and breaking the branch local circuits of the transmitter at the key b the ratchet elect ro-magnet E and printing electro-magnet D of the transmitters and receivers will be actuated, and the papercarriages will be moved simultaneously to space between paragraphs,.the blank on the type- Wheels at unison preventing the making of impressions.

The apparatus and electrical circuits for maintaining the paper-carriages in unison, and for placing any one or more of a series of receivinginstrnments in circuit, and for cutting the operative parts out of circuit in the receiving-instruments for releasing the papercarriage, and for feeding the paper between lines at any point in its excursion, will now be explained.

When the paper-carriageA is released and recoils to the initial point of its excursion, an arm, a, attached to the frame of the papercarriage, strikes the circuit-springs 0 and o of the automatic double-circuit switch 0, closing them against the back contacts 0 and 0, break ing the main-line circuits and closing the branch lines Z and Z, one line, Z, passing through one branch of the differential electromagnet X and independent electromagnet Y, and by line Z into the spring 8" of the commutator S, and the other line, Z, in a reverse direction through the other coils of the differential electromagnet X and the independent electro-magnet Y, line Z. circuit-spring s".

A circuit-breaker, V, Fig. 10, with a pointer, w, arm w, and notched rim to", is attached to each transmitter in a branch of one of the main-line circuits.

To the platform A, or elsewhere in each instrument used as a receiver or transmitter. are secured the differential electro-magnets X X and independent electro-magnets Y Y, one coil of each of the electromagnets X and Y being in connection with the circuit-breaker \V through the binding-post 1), lines Z and Z, spring 8, line Z independent clectro-magnet Y, differential electro-magnet X, line Z, circuitsprings 0 0, line Z, circuit springs z 2 and line Z to the binding-post p. The other branch of the main line is connected from the binding-post 1) through the electro-magnets X and Y by line Z one branch of the doublecircuit breaker b normally-open line Z, circuit-spring .9 line Z, through the branch Y of the independent electro-magnet Y, and in a reverse direction through the differential electro-magnet X, line Z, circuit-springs 0 and 0 of the automatic circuit-breaker 0, line Z circuit-springs Z3 z, line Z and to the bindingpost f.

A branch line, Z, from the arm of key If, normally open, connects line Z with line Z, through this key when depressed. \Vhen the key I)" is closed, it connects line Z with line Z. Lines Z and Z connect lines Z and Z with lines Z and Z when the double-circuit-closing device b is closed.

The individualizing circuit-breaker may have any number of divisionsthat is to say, metallic contacts and insulations. The one shown in Fig. 10 of thedrawings has twentyfour divisions, w representing metallic contacts or makes, and w" insulations or breaks. This individualizing circuit-breaker \V has a metallic hub, 10 insulated from its shaft, and

insulated springs to to for effecting contacts of makes and breaks corresponding with the metallic contacts to" and insnlations w on the periphery of the circuit-breakerNV. The insulated spring'w bears upon the metallic hub to in electrical connection with the contacts'w. The arm w and the pointer to are rigidly attached to the shaft of this circuit breaker. A spring-click, w, is attached to the arm w, and the rim w of the dial-plate is serrated with as many notches as there are metallic contacts on the circuit-breaker \V.

The dial 10 should be numbered with figures corresponding with the number of insulations on the circuit-breaker \V. \Vhen the index to indicates Zero on the dial-plate, the individualizing circuitcloser U on the platform A of all the instruments in the series should likewise stand at unison or zero, and the circuit-springs 10" should bear on an insulation on the circuit-breaker W.

The individualizing circuit-closer U is carried on a shaft, it", supportedin bearings it and a, attached to the platform A and carrying the double-circuit breaker U, the spiral or fnsee a Fig. 7, the ratchetwheel u", the metallic hubs n and 16 of the circuit'closers insulated from each other and from the shaft at This circuit-closer U has metallic contacts a a at corresponding points in their peripheries and in electrical connection with their respective hubs n and u'. The insulated springs a u bear on the hubs, and the springs 10 and a bear 011 the periphery of the circuit-closer U.

The armature a of the electro-magnet X is attached to a bent lever, a supported in trunnions a and a, which lever actuates a pawl, a, when the eleetro-magnet X is energized by the lines Z Z and branch lines Z and Z, leading from the circuit-brcaker \V of the transmitter, and revolves the ratchet-wheel a one notch at each make and break of circuit. There are, however, as many notches on the ratchet-wheel 16 as there are contacts on the circuit-breaker XV. A click attached to the platform A prevents the retrograde movement ofthe ratchet-wheel a A tongue, to, pivoted in trunnions it, is solicited laterally and vertically downward by suitable springs, a and it, causing the tongue u to travel laterally by the rotation of the spiral or fusee u until it arrests the shaft a by contact with the pin it. The armature a of the independent electro-magnets Y and Y is attached to a bent lever, a supported in trunnions if. A retractile spring, a, is adjusted so as to resist the attraction of the single coil of the electro-magnet Y.

Bl revolving the arm 10 of the circuitbreaker \V twice, (the double switch 0 being open, as described,)and thereby sending pulsations through the coils of the electro-magnets X and Y, the arm a will come into contact with the pin u on the fusee or spiralu in all the instruments and arrest the circuit-closers U in unison with the circuit-breaker W. Of course, it will be understood that the index in of the dialplate must point to zero when the circuit-closers are at unison.

When the key 1) is depressed, and the circuits are simultaneously closed through lines Z", Z, Z, Z*, Z, and Z and electro-magnets Y and Y, the armature M will be attracted, while the clectro-magnets XX will neutralize each other, and the bent lever 10 will release the unison arm or tongue a from the stop a, and the springs to a of the arm a will return this tongue to its initial point, ready to commence its travel anew.

The metallic contacts a and a on the circuit-closer U are set at any number that may be desiredsay at No. lso as to be brought into contact with thesprings a and a when the ratchet-wheel a is moved one notch to close the main line circuit of the first receiver through springs 14, 10, a", and a and lines Z" Z Z Z around the automatic switch 0.

Each instrument in theline has its metallic points a and a of the circuit-closer U set one division behind that of the metallic points on the circuit-closer of the preceding one, so that by turning the circuit-breaker W each in strument in line is successively brought into and cut out of circuit until the instrument is reached upon which it may be desired to record impressions.

The method and manner of spacing between lines at any point in the excursion of the papercarriage will now be described.

A square or feathered shaft, k is held within and supported by hearings on the frame A of the carriage, moving therewith during its excursion. To this shaft 70 is secured an arm, 75, bifurcated at one end and engaging with a link, it bymeans ofsuitable bearings. The arm k,held laterally by the arms lc",has a square or feathered hole permitting the shaft k to move freely through it, yet preventing any rotation of it therein. A link, k connects the arm 7a to the bent lever is of the armature 7c" of the electromagnet K. On the extremities of the shaft 70 are fixed arms 70, carrying pawls It, held incontact with the ratchets a by the spring 70 Upon the depression of the key I) when the instruments in circuit stand at unison, and the main lines are broken at the circuit-breakers N N, but closed at the double switch, 0, the branch lines Z and Z are closed at the spring 8 and thence through lines Z Z Z Z Z l to the binding-postp into the main-line circuit. This pulsation energizes the electro-magnet K, and turns the ratchet a of the feed-roller (0 one notch, feeding the paper the space be-' tween two lines.

To release the paper-carriage at any point in its excursion, the key I) is depressed while the mainline circuits are open at the circuitbreakers N N at unison, closing the branch main lines Z and 1" through the spring 8 of the commutator S, thence by linel to the magnet L,and bylines Z Z 1 Z to thebintling-postp",and

thence to the other instruments in circuit or to ground. Then the magnet L is energized by a pulsation on this line, its armature L, attached to its lever a, linked to an arm, a, pivoted to the shaft a, Fig. 6, or the armature L may be secured to the arm a, as shown in Figs. 8 and 9, secured to the shaft of the automatic releasing T-shaped bar a, is attracted, oscillating this Tshaped bar laterally, and causing it to be locked by the spring-latch to, engaging with the pin a. This movement of the T-shaped bar a causes the pins (6 and a to release the dog a and pawl a from the rack A, permitting the carriage at any point in its excursion to return to its initial point for presenting the left-hand margin of the paper to the type-wheel. The recoil of the carriage releases the T-shaped bar from its spring-latch a, as hereinabove fully explained. v

- scribed, and

The paper-carriage of the instruments connected in circuit are brought to unison by sending successive pulsations over both lines by depressing the key b while the type-wheels are at unison, which closes the branch local circuit. through the relay G, thus closing both lines simultaneously and energizing the ratchet electro-magnetE, as hereinbefore described, on both the transmitting and receiving instruments. .This causes the respective paper-carriages to travel until automatically released; or all the paper-carriages in the series may be released by depressing thekey b When the paper-carriages recoil, the arm a attached to the frame a of the carriagerstrikes the springs 0'0 of the automatic double switch 0, breaking the mainline circuits through the compound relays H H, as previously de closing the branch circuits through the differential and independent electro-magnets XX andYY, respectively. The local circuit through the ratchet electro-magnet E cannot now be closed by the compound relays H H. The. individualizing circuitclosers U are thcn'revolved by turning the circuitbreaker W until the branch lines 1*, Z, Z, and Z are closed around the double switch 0, which again restores the main-line circuits through the compound relays H H. This switch 0 is thereafter closed by the first movement of the papercarriage A which restores the main-line circuits through the double switch 0. The paper-carriages of the respective instruments will now, of course, starton their excursion in unison, and at each recoil movement of said carriages the interruption of the main-line circuits by the circuitbreakers Z will indicate to the operator the moment when each carriage is returning to its,

initial startingpoint.

The main-line circuits for operating the magnets H, I, J, K, L, X, and Y by main-line batteries have been hereinbcfore fully described; but I do not, however, confine myself to such method of operating them, as these magnets may be energizedaud operated by local-battery circuits controlled by relays in the main lines, in a manner well understood by persons skilled in electrical science.
